Big ugly build changes might be needed for Debian/Ubuntu

[Scott Ritchie]

So, multiarch is going along well in Debian/Ubuntu, and by next distro
release Wine should be building as a proper multiarch package.  Previous
hacks like ia32-libs will be dead for good.


A side effect of this change, however, is the current build daemons ONLY
have packages for one architecture.  This means that, at build time, you
won't be able to pull in the 32-bit packages on a 64-bit build daemon.
